Model 4080

Total Hydrocarbon in Water Analyzer​​​​


The Model 4080 is designed to detect hydrocarbons (C1-C9+) which may not absorb in the UV region)​

4000 Series Overview:

All 4000 series units employ the same basic architecture and electronics; however, each analyzer has additional features:

​4020 Total Hydrocarbon Analyzer

​Uses FID to measure total hydrocarbons in ppm in a sample gas stream

​4030 Total Hydrocarbon Analyzer

​Basic 40​​20 with sample system at a higher temperature for heated applications

Avoids condensation of the sample

​4040 Methane / Non-Methane

​Basic 4020, plus temperature-controlled sampling system with GC column to give accurate readings of both methane and non-methane hydrocarbons in a gas stream

4060 Benzene Analyzer

​Same as 4040, but used to measure ppb levels of benzene instead of methane/non-methane

4080 Total Hydrocarbon Analyzer

​Basic 4020 with sample system including stripper to measure total hydrocarbons in an aqueous sample​


  • Designed to detect hydrocarbons (C1 - C9+) which may not absorb in UV region

  • Temperature controlled stripper system effectively strips hydrocarbons from water by cross flowing N2 over the packed stripper column.

  • ​Includes Drier Assembly to ensure a dry sample gas is delivered to the analyzer

  • Model 4020 THC analyzer to measure trace THC in gas phase

  • Standard ranges : 0-10, 0-100, 0-1,000 ppm hydrocarbons (methane equivalent)

  • ​Output: 0-1 VDC and 4-20 mADC, Isolated current output

  • Fuel: Mixture of 40% hydrogen / 60% nitrogen

  • Two user configurable alarm points and corresponding relays

  • Electronic flame guard circuit and fuel shut-off solenoid valve

  • Dual-sided, free standing rack with Stripper Sample System mounted on the backside and Model 4020 NEMA-4 enclosure provided on front

  • Optional configurations with sunshade and all components on front panel are available​
